我有一个问题,在android的多屏幕。
在我读完这个网页后:
https://developer.android.com/guide/practices/screens_support.html developer.android.com/training/multiscreen/screensizes.html
我尝试通过添加最小屏幕宽度布局目录将我的活动更改为多屏幕布局:
布局-sw320dp
布局-sw320dp-land
布局-sw480dp
布局-sw480dp-land
布局-sw600dp
布局-sw600dp-land
布局-sw720dp
布局-sw720dp-land
我的活动:

例如,我的问题是在“布局-sw320dp”中,当我将设备更改为nexus4或nexus5x的布局变得不合适时,我为nexus5x设计布局。

您正在设置固定宽度的按钮。这永远不会在各种设备上很好地工作。使用另一种技术。例如,如果你想要4个大小相等的按钮,将每一行作为线性布局,并为它们分配0dp的宽度和1的权重,这样它们就会变得同样大。

您可以创建线性布局并使用可在多个屏幕中使用的加权和.so
